This vulnerability allows a remote attacker to bypass `Transfer-Encoding` header validation by splitting the `Transfer-Encoding` field across multiple headers, with the last field containing a non-final transfer coding like `gzip` or `deflate`. This bypass can lead to HTTP request smuggling, enabling attackers to bypass security controls, desynchronize request processing, or cause requests to be processed in an unintended context.","score":6.5,"severity":"medium","published":"2026-09-18T14:44:00.077Z","modified":"2026-11-06T17:27:30.761Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Red
